Title (EN) METHOD FOR FRACTURING USING A BUOYANT ADDITIVE FOR PROPPANT TRANSPORT AND SUSPENSION
(FR) PROCÉDÉ DE FRACTURATION UTILISANT UN ADDITIF DE FLOTTAISON POUR LE TRANSPORT ET LA MISE EN SUSPENSION D'UN AGENT DE SOUTÈNEMENT
Abstract:
(EN) The transport and suspension of proppant in a fracturing fluid used to fracture a subterranean formation is improved by incorporating a buoyant additive into a carrier fluid that also comprises a proppant. The buoyant additive has a surface, in one non-limiting embodiment a hydrophobic surface or a superhydrophobic surface, and the buoyant additive is present in an amount effective to suspend at least a portion of the proppant in the fracturing fluid. The buoyant additive has had its surface modified with a surface modifying agent, which may include, but is not necessarily limited to, wax, silica, an organo silane, a siliconate, a silicate, a silsesquioxane, phosphonic acids, transition metal oxides, post-transition metal oxides, silicon, and combinations thereof.
(FR) Le transport et la mise en suspension d'un agent de soutènement dans un fluide de fracturation utilisé pour fracturer une formation souterraine sont améliorés par l'incorporation d'un additif de flottaison dans un fluide porteur qui comprend également un agent de soutènement. L'additif de flottaison présente, dans un mode de réalisation non limitatif, une surface hydrophobe ou une surface superhydrophobe, et l'additif de flottaison est présent en quantité efficace pour la mise en suspension d'au moins une partie de l'agent de soutènement dans le fluide de fracturation. La surface de l'additif de flottaison a été modifiée à l'aide d'un agent modificateur de surface, qui peut comprendre, mais sans nécessairement y être limité, une cire, de la silice, un organosilane, un siliconate, un silicate, un silsesquioxane, des acides phosphoniques, des oxydes de métaux de transition, des oxydes de métaux de post-transition, du silicium et des combinaisons de ceux-ci.
